So what can we actually ascertain about a student with an NCEA qualification?

Very little, according to the Initiative’s second report, Score! Transforming NCEA Data. It brought to attention the huge variation in grade distribution across subject sub-fields. It is comparatively easier to gain an Excellence grade in Languages and Performing Arts than it is in Mathematics and Statistics. And not surprisingly, they found that more students pass internal assessments than external assessments.

In an attempt to redress these imbalances, the economists at the Initiative came up with a Weighted Relative Performance Index (WRPI) that endeavours to make “sense” of a student’s NCEA credits and provide a fairer comparison of performance between students. 1

It was a laudable attempt. However, one blatant inequity in the NCEA system that was not addressed by the WRPI, and has yet to be discussed widely, is the absence of a sensible time restriction applied to individual external assessments.

Allow me to explain. In Mathematics, students at any of the three NCEA Levels may be entered for a three-hour external examination comprising up to three achievement standards. Each achievement standard is a self-contained assessment/paper, sealed up in its own plastic wrapping. (Biodegradable, I hope.)

It would seem reasonable that each of the three papers should be completed in approximately one hour. 2 Therefore, it would seem reasonable that if a school decides to enter a student for fewer than three achievement standards, then the duration of the exam should be reduced, i.e. one hour for one paper, two hours for two papers. But no, not with NCEA! Schools may enter students for one or two papers, and students still get three hours to complete them!

This obviously puts students entered for three papers at a disadvantage. Are these students supposed to console themselves that they are receiving a better education, even if their peers come out with higher grades because they had more time?

Schools can, and do, game the system by entering their students for fewer than three papers. But students can also game the system by electing to not attempt all of the papers for which they are entered. If they leave the plastic wrapping intact, they will receive a Standard Not Attempted/Assessed (SNA), and apparently this is better than a Not Achieved (N).

Really?? According to this memo, it’s better for schools because School Result Summaries will include N’s but not SNA’s. Also, SNA allows for the possibility that “a student ran out of time so an N would not be a fair result”. In other words, it’s better to fail to try than to try and fail.

For those chasing an Endorsement, it is actually in their best interests to attempt fewer papers and go for higher grades. For example, for a student chasing an Excellence endorsement, two Excellence grades would be preferable to three Merit grades.

Our national secondary school examination system actually rewards students for doing less work.

The acknowledgement of effort is lacking even within an individual paper. In a traditional marking scheme, every correct answer would contribute to the final mark, but NCEA is a standards-based assessment system with “top down” marking. 3 Therefore, confident students can take a gamble and jump straight to the harder parts of a question. It’s a risky strategy, but if it pays off, they may achieve Excellence having answered roughly a third of the paper. This flies in the face of the instruction printed on the cover page: “You should attempt ALL the questions in this booklet.” If you do well, then some of what you do could turn out to be a waste of time.

NCEA is a system that does little to incentivise students to put in maximum effort or to persevere if the results are likely to be sub-optimal. Until these problems are addressed, mediocrity will prevail. We welcome the Ministry of Education’s review of NCEA this year, and hope to be part of that discussion.

1 Ironically, NZQA in their utopian socialist bubble didn’t want us to compare students, but it’s happening anyway. Students compare themselves, universities have already come up with their own weighted metrics, and employers are learning that “E” grades on a Record of Achievement are actually higher than “A” grades.

2 Prior to 2013, each paper used to start with the recommendation “You are advised to spend 60 minutes answering the questions in this booklet.”, but not any more.

3 Anecdotally, not all markers appear to follow this methodology. Perhaps they too feel that any positive efforts should be acknowledged, even if ultimately ignored in the final score.

It’s time for New Zealand to look past the hysterical response to this year’s NCEA Level 1 MCAT exam and try to understand what’s really going on here.

Was the exam appropriate in level and difficulty?

In my previous post, I analysed the second of the two (supposedly) parallel papers and found that most of the questions were at a reasonable level for NCEA Level 1, and also reflective of the title “Apply algebraic procedures in solving problems”.

There was a section that was more investigative in nature and new for MCAT (but such questions have appeared in other Level 1 maths assessments in the past). This section was made difficult by its poor construction and confusing wording, and most Level 1 students would have struggled to understand the intention. But most exams have a Very Hard Question (VHQ), so I guess this is the VHQ for this exam.

Was it too different from previous years?

Apart from the investigative question, I don’t think so, but I might have said differently last year, when there was a noticeable step up. From the 2015 MCAT Exemplar:

“This year at least one of the three questions will not have any directed straight procedure-based parts and the other questions a maximum of one such part.…candidates will not be able to provide evidence by following a direction to solve factorised quadratics, factorise, expand, write or solve a linear equation, or simplify an expression involving the collection of like terms in response to being told to. One part in each question may direct the student to perform such procedures; but without further evidence at Achievement level, this will not be sufficient for the award of the standard. Utilising procedures such as factorising, simplifying a rational function, or writing an equation from a word problem will provide evidence of solving a problem. Candidates must know that given a word problem, they will be required to write equation(s) and demonstrate consistent use of these in solving a problem. Candidates will be expected to have a basic understanding of the relationship between a quadratic function and the associated graph.”

MCAT was last reviewed in 2013 and is up for review at the end of this year. Whether a change in style between reviews is appropriate should certainly be up for discussion.

So why did students find it so difficult?

The unfortunate reality is that students did struggle with this exam. The gap between what MCAT is expecting of students, and what students are actually capable of, is widening.

There are complaints that the lack of “gimme” questions at the start of the paper has left students “shell-shocked” and “killed” their confidence. Are we seriously saying that our students are capable of factorising a quadratic when explicitly told to do so, but they are unable to decode a basic word problem and factorise a supplied quadratic expression for themselves, even though they probably wouldn’t know of anything else to do with an expanded quadratic? What does this say about the resourcefulness or resilience of our students?

We cannot blame this year’s Level 1 maths teachers for what has happened, and they should rightly feel insulted. The problem started many years before this one.

What we’re really seeing here is the fruits of a flawed primary maths curriculum floating its way through the system. Even two and a half years at secondary school isn’t enough to turn things around. The damage is too great.

If you look at what the Numeracy Project was trying to achieve at primary school level, our secondary school students should, by all accounts, be highly numerate problem solvers, but in fact they are worryingly innumerate and apparently not very good problem solvers either. It’s ironic that one of the big selling points of this “new approach” to teaching maths was the development of early “Algebraic Thinking”. I think we can safely call that a Not Achieved.

A systemic failure in mathematics education is playing out before our very eyes. NZQA is trying to inch up the standard, year by year, when the reality is that students are actually getting worse at algebra, year by year. When students are struggling to master the basics, it’s hard to see how teachers can lift their students to the higher levels of problem solving now expected.

Given that next year’s Year 11 students will be the same generation of 9-year-olds who performed so abysmally in TIMSS 2011, alarm bells should be ringing loudly. It would not be surprising if fewer students were entered for next year’s MCAT.

Spring forward, fall back

NZQA could make the MCAT easier again, but that would be disappointing. I believe this year’s MCAT is the standard we should be aspiring to. If the examination team could tighten up on the construction of certain questions, the MCAT would be an examination to be proud of on the world stage. (The assessment side of things, however, needs a lot more work.)

The best thing NZQA can do is go back to examining algebra at the end of the year.

September is a really bad time of year for students to face their first high-stakes external examination. Some students barely appreciate its significance when it is tangled up with mock exams for other topics and different subjects, and the ones that do appreciate its significance prioritise the MCAT at the expense of preparing for their mock exams.

The sensible thing to do, surely, is to fold it in with “Tables, Equations and Graphs”. We’re already seeing questions about graphs in the MCAT anyway, and why shouldn’t we? Algebra and Graphs are not separate topics, they are inextricably tied. As we now see, NCEA’s compartmentalising of topics as separate assessments is hurting students’ ability to make connections and become effective problem solvers.

The decision to deliver the assessment earlier in the year and have it administered by the schools has a distinct whiff of cost-cutting about it, but it has been a disaster for maths education and is costing the country dearly. If we want students to pursue STEM subjects at university, we need to give them every chance of succeeding in algebra at Level 1, as this effectively marks the fork in the road between calculus and statistics at Level 2. If we want to increase the “dollar value” of Kiwis contributing to New Zealand’s economy, fixing our maths education system is a very good place to start.

The media is buzzing with excitement over last week’s NCEA Level 1 MCAT (Mathematics Common Assessment Task) examination. Students are in tears and teachers are outraged over the exam that was “very different in style” and “far too difficult”.

For those who don’t know what the MCAT is, or why the MCAT might be so important, here are some salient facts:

This is an external NZQA exam, administered internally by the high schools in September. Prior to 2011, algebra was examined in November, as part of the three-hour end-of-year external exam.

Calculators are NOT allowed in this examination.

Schools may struggle to administer the exam in a single day, so there are two similar, but different, versions of the exam – one to be delivered on a Tuesday, the other on a Thursday.

The traditional assessment (as opposed to the trial online EMCAT) was made harder last year. From the official NZQA assessment (marking) schedule: “The style of some of the questions in this year’s assessment has changed so as to align more closely with the requirements of the achievement standard. The title of the standard requires the candidate to use algebraic procedures in solving problems.”

Students who don’t do well in algebra at NCEA Level 1 will have limited options at NCEA Level 2. Such students are typically not allowed to study calculus at Level 2.

Students who don’t do well in algebra will struggle with calculus.

Students who don’t do well in algebra or calculus will find it difficult to pursue STEM subjects at university.

So just how different or difficult was the exam? Now that the papers are in the public domain, I will review one of them (the Thursday paper) here. If you aren’t interested in the details, you can skip to the conclusion here.

[Update: I have seen the assessment (marking) schedule and added comments below. As with most NCEA exams, it’s not the questions I have so much of a problem with, it’s how they are assessed…]

The intention here is probably for students to factorise the quadratic as and supply the two factors as the side lengths. However, I suspect the examination team failed to notice that this question has infinitely many possible answers. For example, another factorisation that students might have reasonably obtained is

The wording of this question should have been sharpened so that the intended factorisation (if there was one) was made clear. (See Question Three (a)(i) below.)

[Update: As predicted, the assessment schedule does not allow for any answer other than the intended factorisation. I pity anyone who offered a different but valid answer.]

Poor wording aside, factorising quadratics is a basic algebraic procedure that is typically introduced to Year 10 students, and this question put a thin veneer of an application on top. Level 1 students should be familiar with applying algebra in the context of measuring area, albeit in the opposite direction. If they knew how to multiply two quantities to form the area of a rectangle, it doesn’t seem unreasonable to expect them to recognise that this question was asking them to reverse that process.

This is a reasonable question. Students at this level should be able to solve a quadratic equation that is not equal to zero to begin with, but can be made equal to zero and then factorised.

[Update: To my surprise, if this question was answered in full, it was worth an Excellence! That should cheer up a few people.]

This is a simultaneous equations question, not trivial, but reasonable.

[Update: If students were able to write down at least one equation correctly, that was worth an Achieved.]

This is a basic procedure, namely adding algebraic fractions. There is hardly anything to do here – they even supply the answer. The subtraction of algebraic fractions appears more commonly in maths exams because students are frequently caught out by multiplication of negative numbers.

This is probably one of the questions that some people are suggesting is more suitable for NCEA Level 2. I am inclined to disagree. Certainly, a general index equation might require logarithms to solve it, but not this one. As long as students recognise that , this question is manageable.

Furthermore, this index question is not much harder than index questions in previous years. Last year’s trial online EMCAT asked “What is the connection between and if ?” Again, as long as students know that , they should be able to say something sensible. In the 2014 MCAT, students were asked to solve .

In summary, I feel that Question One is fair. Part (a)(i) might have deviated from early questions in past papers of the “Factorise this” or “Simplify that” variety, but the application was not particularly difficult or surprising. As NZQA pointed out last year, the title of the standard is “Apply algebraic procedures in solving problems”.

This question is an algebraic substitution question. The fact that the equation modelled a parabola is again a thin veneer of an application. If students didn’t know what a parabola was, I hope they managed to ignore it and press on.

Solving algebraic inequalities seems to unsettle students, even though the steps required are almost identical to the steps required to solve algebraic equations – there is only one extra thing to remember, which is to reverse the inequality if multiplying or dividing by a negative number. All steps required to solve this question should be known to students at this level. [Update: Even just one correct expansion was worth an Achieved.]

Interestingly, this was one of the few occasions where the parallel question in the Tuesday paper was noticeably trickier at first appearance, because there were identical factors on both sides of the inequality and it might have been tempting to cancel them out. Unfortunately, that would have led to something nonsensical. The lack of equivalence between these parallel questions is something that should have been picked up by the examination team and corrected.

This is potentially another question that looks like a Level 2 question, but isn’t. A reasonable first attempt at solving this would be to rewrite the inequality as . A sharp observer might notice that

Either way, as long as students know their powers of 2 up to 32, they should see that the whole number has to be less than or equal to 5. As noted above, index questions of this type have been asked in previous years. Changing an equality symbol to an inequality symbol does not affect the algebra required to solve the problem.

This question requires students to expand and simplify two expressions and then look for similarities between them. If students had seen a similar 2014 MCAT question, in which students were asked to write in terms of , then they would have been adequately prepared to attempt this question. [Update: Even just one correct expansion was worth an Achieved.]

OK, this is where things start to get interesting! Students were given 9 lines of paper in which to conduct their investigation and answer this part of the question.

Firstly, what is meant by “when Janine changes the order of the numbers in Line 1”? The directness of the question “Does she get the same answer as in Line 4?” suggests that we are supposed to investigate a single event. But there are 23 ways in which Janine could change the order of the numbers. Are students expected to try all 23 ways? Over 9 lines of paper, probably not. If we are meant to infer that Janine changes the numbers only once, how can we possibly investigate if we don’t know what the new order looks like? The wording of the question is decidedly murky.

In actual fact, the answer is “yes” or “no”, depending on how the numbers are re-ordered. I’ve seen probability questions in which a “yes” is an Achieved answer but a “no” is a Merit answer, but at this early stage in this question, students would be choosing a new order at random, so it would be unfair if either answer fell into a different achievement band.

[Update: If you tried one rearrangement and said “yes” or “no”, that was worth an Achieved. So even though I understood the question well enough to perform a succinct investigation with the preferable answer of “no”, I would have only gotten an Achieved. If you tried two rearrangements but didn’t say anything, that was also an Achieved. The wording of the Merit criteria is just as nonsensical as the question, but I think they want at least two rearrangements with a point of difference and some sort of statement about one’s findings.]

I had to parse this sentence many times and came to the conclusion that it doesn’t make a lot of sense, even after tweaking it to read “Find, using algebra, the relationship between the numbers in Line 1 and the numbers in Line 4 when she changes the order of the numbers in Line 1.” If students are meant to investigate what happens to the expression for the number in Line 4 after the numbers are changed, then it has not been made very clear. A better question would be “Using algebra, show how the number in Line 4 might be affected if Janine changes the order of the numbers in Line 1.”

This question doesn’t feel like problem solving. We are using algebra to make a general observation. Students at Level 1 will have very little experience of using algebra in this way, but such questions have been seen in other Level 1 Maths assessments in the past, namely “Tables, Equations and Graphs”, an end-of-year assessment concerned specifically with the application of algebra to graphs.

It is certainly possible to express the number in Line 4 in terms of the numbers in Line 1 at any given point in time. For example, if the numbers in Line 1 are called , then the number in Line 4 is . But perhaps we are supposed to pay attention to the pattern of the example numbers 2, 4, 6, 8 and call the numbers ? Is this important or is this a distraction?

I would conjecture that a student would be better able to answer part (i) after answering part (ii). That is the whole point of algebra, after all. It enables us to see patterns in numbers, or at least understand better the patterns that we see, because the numbers themselves often get in the way. Assuming there is a pattern in the numbers in Line 1 gets in the way of truly understanding any pattern that might be observed in the triangular formation, and ideally we should not be distracted by this. So my preferred setting of the first two parts of Question Two would be split into three parts:

Janine changed the order of the numbers in Line 1 and found that it changed the number in Line 4. What might Janine’s new ordering look like?

Janine wonders whether changing the order of the numbers in Line 1 will always change the number in Line 4. Use algebra to find the relationship between arbitrary numbers in Line 1 and the resulting number in Line 4.

Use your expression for the number in Line 4 to explain how Janine could change the order of the numbers in Line 1 but not change the number in Line 4.

If students were brave enough to attempt this question, hats off to them! I quite enjoyed this question myself, but only students with a good understanding of divisibility would understand how to interpret the algebra in this question. Furthermore, open questions such as “what do you know?” are only fair if the answers are marked “openly”. Unfortunately, that’s not the case with NCEA. They still have something specific in mind, answered to a greater (Excellence) or lesser (Achieved) extent, or somewhere in the middle (Merit). Therefore, students should reasonably expect to be given better guidance as to what is intended by the question. E.g. “If the number in Line 4 is divisible by 3, then identify the position of the number or numbers in Line 1 that are divisible by 3.”

My final comment about this question is the lack of continuity. In part (iii), we were to assume there was a pattern in the numbers in Line 1, but it wasn’t the pattern demonstrated at the start of the question. It appears that the 2, 4, 6, 8 pattern was a red herring, and the examination team should have chosen numbers that appeared to be more random.

In summary, Question Two was fair up to part (d). Part (e) was poorly written and too hard for Level 1.

This question is almost identical to Question One (a)(i) but it has an important difference. One of the side lengths is given, which means the intended factorisation of the quadratic expression for the area has been made clear. It begs the question, why was Question One (a)(i) even included??

Another open question! What’s wrong with “State any restrictions on the value of for this rectangle”?

[Update: This is amazing. If you answer the question correctly, you only get an Achieved. If you say something about the area or the side lengths, i.e. more than was asked for, you get a Merit! If they wanted commentary on the area or the side lengths, why didn’t they just say “Explain.” at the end?]

This is a “changing the subject of the formula” question, and there have always been questions of this type in previous years.

Er, what’s this question doing here? This is the sort of basic procedural question that would have been better placed as Question One (a)(i).

This is not a trivial question, but it is suitable for Level 1. However, it’s worth noting that the parallel question in the Tuesday paper resulted in a quadratic equation that was different enough to be inequivalent. The Tuesday students may have struggled more than the Thursday students. This should not have happened.

[Update: Sure enough, the Tuesday question must have been done very badly, because you could get Excellence even if you didn’t quite solve the equation! I’ve also heard reports of students (not ours!) getting caught up trying to calculate the square root of 8 without a calculator…]

If students weren’t sure how to answer this question, looking at (ii) would have given them a good clue!

Like many NCEA questions, this is quite ‘wordy’ and requires a high level of literacy to understand the question. It also requires knowledge about the features of the graph of a quadratic expression, and the use of algebra to solve a quadratic equation. The icing on the cake is to form a percentage from the two quantities obtained (the maximum horizontal width and the width at a vertical depth of 3cm).

[Update: Solving the equation, i.e. bulk of the work and the algebraic heart of the problem, was only worth a Merit. The trivial step of calculating a numerical percentage at the end was what it took to get an Excellence. Seriously?? Where is the extended abstract thinking in there? I suspect the examination team pulled this question from a traditional “marks out of 100” paper but failed to modify it for NCEA.]

Although I think this is a reasonable Excellence question for this assessment, it is worth noting that this question could easily appear in the “Tables, Equations and Graphs” assessment at the end of the year. There needs to be some discussion about whether or not teachers and students should expect the same knowledge to be potentially assessed twice.

It seems that some schools had not yet taught their students about graphs, but in all fairness, last year’s MCAT exam had questions that required graphing knowledge.

In summary, Question Three was challenging but fair, provided students had been taught the appropriate material.

In conclusion…

This exam wasn’t a walk in the park, but actually most of the questions were fair for Level 1, even if they weren’t identical in form to past exam questions. There were certainly some poorly-worded questions, but unfortunately I see them in NCEA maths exams every year. MCAT 2016 is by no means the exception.

It is true that the MCAT now has fewer basic questions that test purely algebraic procedures, but most of these procedures should be introduced in Year 10, so it is not unreasonable to expect students be ready to apply them in Year 11. Given that the change in style occurred last year, I am surprised that the huge uproar didn’t occur 12 months ago.

Most importantly, I believe this year’s MCAT is the standard we should be aspiring to. Media reports suggest the reality in schools is very different. I will discuss this in my next post.

“Show your working” is a common request in high school maths exams. Yet, in the modern learning environment, where worksheets and workbooks are common place, students don’t get a lot of practice at this important communication skill. With so much content to deliver, there is little time left for teachers to teach students how to craft a good solution. Furthermore, textbooks with answers at the back generally do not show any working. It’s no wonder so many students find writing out mathematics both difficult and puzzling.

So, why should you bother to show your working? Here are some points worth considering.

In a written exam, there is no kudos in working everything out in your head or getting the wrong answer quickly. It gets you no extra marks. In fact, if working is required, writing down only the final answer willcost you marks.

Getting the right answer is not as important as understanding the steps you took to get there. That’s not to say that getting the right answer isn’t important. Quite the opposite. It’s so important that you want to be confident you’ll be able to get the right answer every time you encounter the same type of question.

Showing your working is not supposed to be a nuisance. It is meant to explain, with justification, how you arrived at your final answer. Rather than being a nuisance, it should actually help both you and your teacher/marker to understand your work better. Whoever is marking your work is not a mind reader. Even you might have trouble understanding what you did when you look back at your work, sometime later, if you haven’t provided enough detail! But if you have made a mistake and the steps are written out clearly, it will be much easier to identify where the misunderstanding occurred and correct the mistake.

Use your brain power wisely. Most students are faster and more accurate when they write things down because they can focus on the accuracy of each step rather than holding everything in their heads. If you think that not showing your working will save you time, think again! What if you make a mistake? You won’t save any time if you get a wrong answer quickly and then have to re-do the calculation. And that’s only if you notice. If you’ve written down your steps, you are more likely to spot any mistakes and only have to re-do part of the calculation.

If, in an exam, you’ve written down nothing but an incorrect answer, you’ll get no marks. However, if you’ve written down an incorrect answer but have shown your working, there is a chance that your marker will be able to find something in there to justify giving you a partial credit. In fact, if you made only a tiny numerical slip, it might be overlooked and you might still be awarded full marks.

Hopefully, you are now convinced that showing your working is a good idea. Here are some tips on how to get started:

Read quality worked solutions, and then practise writing out solutions in a similar manner.

Articulating your ideas in writing helps you to understand better what you are doing. You need to start practising this skill with the easy questions, when you know what all the steps are. If you can’t do it for the easy questions, you won’t be able to do it for the harder questions either! In actual fact, the harder questions might not be as hard as you think, if you are well practised at breaking down a problem into smaller steps.

Knowing how much working to show requires a bit of judgement. Again, refer to quality worked solutions for guidance. Here is a good rule of thumb: when you are writing out a solution, imagine that the person reading your solution is someone in your class who doesn’t know how to solve the problem. Would that person be able to follow your solution and then understand how to solve the problem? Try it yourself: swap solutions with a friend and see if you can understand each other’s solutions. It might give you a better appreciation of what it takes to write a clear and coherent solution if you try reading someone else’s work.

Solving word problems is generally a test of whether you can extract information from the question and apply it correctly. So, identify when you are making explicit use of information or numbers supplied in the question and make this clear in your solution. For example, if you are calculating the area of a circle with diameter 6cm, a good written solution might be:

Radius r = × 6cm = 3cm

Area of the circle = πr2 = π × 32 = 28.27cm2

Understand the precise meaning of the equals sign (=) and use it correctly. The equals sign does not mean “Here is the answer:” or “Here is my next line of working:”. The equals sign means “is equal to” or “has the same value as”. Naturally, as the words suggest, it only makes sense to use the equals sign to indicate that two expressions (not equations) are equivalent or have the same value. For example, if I wanted to multiply 3 by 4 and then add 17, I would write:
3 x 4 + 17 = 12 + 17 = 29

and not: 3 x 4 = 12 + 17 = 29. The latter is what I call a running calculation. It might be how we think through the calculation in our heads, but, as written, it is nonsense because it says that 3 x 4 is the same as 12 + 17.

The benefits of writing out your mathematics solutions in full cannot be understated. With continued practice, you will understand things better and have more certainty of your answers, particularly when attempting harder questions. Ultimately, you will feel better prepared and more confident when you go into your exams.

We have a spat between our tertiary engineering schools and our secondary schools/NZQA. It’s time to bang some heads together.

Unfortunately, it’s true. I respect NCEA, but its structure does not support student achievement in algebra, and hence calculus, and recent revisions to NCEA standards have reduced the examinable content in these core topics. It’s a real concern because New Zealand desperately needs more science, technology and engineering.

On the other hand, the engineering schools should raise the bar if students attaining “Achieved” grades are under-prepared. The bar should never have been lowered in the first place! Every NCEA student wanting to continue with their studies should be aiming for “Merit” or higher.

But wait a minute. Secondary students are under-prepared for their studies too! PISA 2012 results are out and New Zealand’s rankings have plummeted (and not just in mathematics). It all starts at primary school…

New Zealand mathematics education is in trouble.

We need to turn things on their heads if we want to prepare school students adequately for tertiary study. The impetus must come from the top. University lecturers should influence what is taught in secondary schools, secondary school teachers should influence what is taught in primary schools. There needs to be a division of responsibility in designing a school mathematics curriculum. The mathematicians should determine the content, the educationists should determine how to deliver that content and ensure that teachers deliver it effectively.

This is my idea for a brighter future for maths education in New Zealand.
